BERLIN -- German prosecutors have imposed a fine of 535 million euros ($598.99 million) on Porsche for neglecting supervisory obligations linked to diesel emissions cheating, they said in a statement on Tuesday.
Prosecutors in the southern city of Stuttgart said that the company's development department had neglected its legal obligations, which ultimately led to the sale of diesel cars in Europe as well as other regions that did not comply with emissions rules.
Porsche, a subsidiary of Volkswagen Group, has not appealed, they said. Porsche confirmed the fine and said that prosecutors' proceedings against the company had now come to an end.
The Porsche brand itself never developed diesel engines but its managers failed to properly supervise their use in the vehicles, leading to the probe, Porsche said.
U.S. authorities disclosed Volkswagen's systematic emissions cheating on Sept. 18, 2015, sparking the biggest business scandal in the company's history which has cost VW Group 30 billion euros in penalties and fines.
VW, Porsche and Audi all sold diesel engine cars that failed to conform to clean air rules and cheated emissions tests.
German prosecutors have pursued individual engineers. They took action against the companies for lack of oversight because managers failed to prevent heavily polluting cars from hitting European roads.
With the settlement, Volkswagen completes its deals with German prosecutors over the sale of rigged cars. VW last year settled with Brunswick investigators for 1 billion euros under the same kind of proceedings and its Audi unit followed by paying 800 million euros to Munich prosecutors.
"Concluding the proceedings is another important step towards ending the diesel topic," the Porsche statement said. "In the fall of 2018, Porsche announced its complete withdrawal from diesel and is fully focused on the development of cutting-edge gasoline engines, high-performance hybrid powertrains and electric mobility."
